So I soldered some 2.54mm pitch pin headers to the lcd, then super glued it to the back of the ph module.

I then connected and soldered the SDA, SCL, VCC, GND pins of the lcd to the SDA, SCL, VCC, and GND pads on the ph module.

I should note that I only used dupont cables because I had already soldered headers. If I was going to do it again I would just solder wires to both ends. Also, the area I applied the superglue to was the inductor.

So connect the SDA,SCL,VCC,GND pins of the ph module to your Arduino. After that, load up this code through the arduino IDE:

Follow the same calibration instructions as in the previous tutorial and now your arduino will display the ph on a screen.
